Policy Proposal 2008-2
IPv4 Transfer Policy Proposal
On 17 October 2008 the ARIN Advisory Council (AC), acting under the
provisions of the ARIN Internet Resource Policy Evaluation Process,
determined that this proposal did not have the support of the community
and decided to abandon it. The AC stated that they are not abandoning
the concept of transfers, however they are abandoning this specific
proposal.
At this time the author of the proposal may elect to use the petition
process to attempt to advance the proposal. The deadline for the author
to initiate a petition is 23:59 EDT, 29 October 2008. If the author
chooses not to petition or the petition is unsuccessful, then the
determination of the AC stands and the proposal is abandoned.

Policy Proposal 2008-2
IPv4 Transfer Policy Proposal
Author: ARIN Advisory Council
Proposal Version: 1.4
Date: 18 September 2008
Proposal type: modify
Policy term: permanent
Policy statement:
Modify the current NRPM section 8 as follows --
8. Transfers
[8.1. Transfers – retain as is]
[8.2 – remove the word “only”, and retitle to “Transfers as an Artifact
of Change in Resource Holder Ownership”]
[Renumber existing 8.3 to 8.2.1 and retitle to “Documentation
Requirements for Transfers as an Artifact of Change in Resource Holder
Ownership”]
[Add the following new section:]
8.3. Simple Transfer of IPv4 Addresses
In light of the pending exhaustion of the IANA IPv4 free pool, ARIN will
also process IPv4 address transfer requests subject to the following
conditions. These conditions apply only to Simple IPv4 transfers, not to
transfers performed according to section 8.2.
8.3.1 Conditions on the transferor (the organization providing addresses
for transfer):
• The transferor has no outstanding balances with ARIN.
• The transferor has not received any IPv4 allocations or assignments
from ARIN (through ordinary allocations or assignments, or through this
Simple Transfer policy) within the preceding 12 months.
• If the transferor elects to retain a portion of a block pursuant to
8.3.6, rather than transferring an entire block, the transferor must
sign (or have previously signed) a RSA or LRSA covering the retained
portion.
8.3.2 Conditions on the transferee (the organization receiving the
transferred addresses):
• The transferee intends to use the transferred IPv4 addresses within
the ARIN service area.
• The transferee has no outstanding balances with ARIN.
• The transferee’s need is confirmed by ARIN, according to current ARIN
policies.
• The transferee signs (or has previously signed) an RSA covering the
IPv4 addresses transferred.
• The transferee may request and receive a contiguous CIDR block large
enough to provide a 12 month supply of IPv4 addresses.
• The transferee may only receive one IPv4 address transfer through this
Simple Transfer process every 6 months.
8.3.3 Conditions on the IPv4 address block to be transferred:
• The IPv4 block must comply with applicable ARIN allocation
requirements, including minimum allocation size. However, an IPv4
allocation or assignment of /24 or larger, but smaller than the current
minimum allocation size, may be transferred as a whole resource (but may
not be subdivided).
• The IPv4 block must currently be registered for use within the ARIN
service area.
• There must be no dispute as to the status of the IPv4 block or
regarding the allocation or assignment of such block to the transferor.
8.3.4 [Section omitted]
8.3.5 Pre-qualification
• An interested transferee must seek pre-qualification from ARIN to
confirm its eligibility to receive a transfer (including satisfaction of
need according to current ARIN policies) before making any solicitation
for transfer. Upon pre-qualification, ARIN will provide the transferee
with documentation of the pre-qualification, including the size (CIDR
prefix length) of the largest IPv4 address block the transferee is
eligible to receive, and the expiration date of the pre-qualification.
• An interested transferor may seek pre-qualification from ARIN to
confirm its eligibility to offer a transfer before offering IPv4 address
resources for transfer. Upon pre-qualification, ARIN will provide the
transferor with documentation of the pre-qualification, including the
network block and the expiration date of the pre-qualification.
8.3.6 De-aggregation when Permitted by ARIN
ARIN may allow transferors to subdivide network blocks. ARIN will
attempt to ensure an adequate supply of small blocks while minimizing
de-aggregation.
8.3.7. Safe Harbor
The fact that an IPv4 address holder is making IPv4 addresses available
for transfer, pursuant to this policy, does not, in and of itself,
indicate that the address holder lacks the need required for an
allocation under ARIN policy.
8.3.8. Organizations under Common Ownership or Control
If an IPv4 transferor or transferee is under common ownership or control
with any other organization that holds one or more IPv4 blocks, the IPv4
transfer request must report all such organizations under common
ownership or control. When evaluating compliance with IPv4 Simple
Transfer conditions, ARIN may consider a transfer request in light of
requests from other organizations under common ownership or control.
8.3.9. Record-keeping and Publication
ARIN will develop and operate a listing service to assist interested
transferors and transferees by providing them a centralized location to
post information about IPv4 blocks available from pre-qualified
transferors and IPv4 blocks needed by pre-qualified transferees.
Participation in the listing service is voluntary.
After completion of a transfer, ARIN will update the registration and
WHOIS records pertaining to the IPv4 block. ARIN will also publish a log
of all transfers, including block, transferor, transferee, and date.
Rationale:
The ARIN Board of Trustees asked the Advisory Council to consider a set
of questions around the depletion of the free pool of IPv4 addresses,
the transition to IPv6 for Internet address needs in the future, and
ARIN's possible role in easing the transition.
Over the course of the year, the Advisory Council has worked to solicit
input from all parts of the policy-making community, through the ARIN
XXI public policy meeting, the Public Policy Mailing List (PPML), sector
meetings, and a poll of PPML subscribers. As a result of the input
received, this policy has been simplified considerably, removing or
modifying text and restrictions deemed unnecessary, while preserving
those aspects that seem to be supported by consensus.
This policy proposal would create a transfer mechanism for IPv4 number
resources between those who have excess resources and those who have a
need, thereby allowing ARIN to continue to serve its mission after IANA
free pool exhaustion. This proposal would also set conditions on such
transfers intended to preserve as much as possible the existing policy
related to efficient, needs-based resource issuance, and would leverage
ARIN's control systems, audit trails, and recognized position as a
trusted agent to avoid speculation and hoarding and diminish the
likelihood and extent of an uncontrolled 'black market' where the risk
and potential for fraud is immeasurably higher.
Many of the transfer conditions are self-explanatory, but some worth
highlighting are that:
• To discourage speculation, a waiting period (proposed at 12 months) is
required before a recipient of space can transfer it to another
organization.
• Transferees must qualify for IPv4 space (just as they do today when
getting it from ARIN) before they can receive address space by transfer,
or solicit space on a listing service.
• To discourage unnecessarily rapid growth of routing tables, an
allocation or assignment may not be arbitrarily deaggregated. To ensure
an adequate supply of small blocks while minimizing deaggregation, ARIN
may allow transferors to subdivide network blocks. A suggested starting
point is to allow transferors to subdivide an IPv4 block into up to four
smaller blocks on CIDR bit-boundaries, provided each resulting block
satisfies the minimum allocation size.
• A transferee may receive one transfer every 6 months, and may receive
at least 12 months worth of space, so they’ll be incented to transfer a
block appropriately sized for their needs, which will further discourage
deaggregation and keep smaller blocks available for smaller organizations.
The proposal would also have ARIN develop and operate a listing service
to facilitate transfers and provide an authoritative central source of
information on space available and requested for transfer. It would not
prohibit private party transactions, but would encourage potential
transferors and transferees be pre-qualified first, so that neither
party will encounter any surprises when they ask ARIN to process the
transfer.
Timetable for implementation: immediately upon ratification by the Board
of Trustees
